Detailed Description
| |||
Statement Reference When expression is driven by Scer\GAL4elav-C155 flies show abnormally outspread wings and cannot fly. Flies are uncoordinated and show adult lethality - dying 5-10 days post-eclosion. When expression is driven by Scer\GAL4Mhc.PW flies' wings are droopy or held up and they cannot fly. When expression is driven by Scer\GAL4G7 flies show pupal lethality. When expression is driven by Scer\GAL4hs.2sev the retina is disordered with misshapen rhabdomeres, abnormal rhabdomere numbers and fused ommatidia. Phototransduction is normal, however synaptic transmission is reduced (as indicated by a reduction in off-transient mean amplitude as assayed by ERG). When expression is driven by Scer\GAL4elav-C155 the larval neuromuscular junction shows pronounced synaptic undergrowth and underelaboration of synaptic terminals. Muscle 4 has 36% decrease in number of boutons over controls. Bouton diameter is nearly twice that of wild type. When expression is driven by Scer\GAL4Mhc.PW the larval neuromuscular junction shows pronounced synaptic undergrowth and underelaboration of synaptic terminals. Muscle 4 has 17% decrease in number of boutons over controls. Mean EJC amplitude is unaffected when expression is driven by Scer\GAL4elav-C155 but mEJC analysis shows that the frequency of spontaneous glutamate release is increased five-fold (though unaffected when driven by Scer\GAL4Mhc.PW). When expression is driven by Scer\GAL4ato.3.6 axon extension from the lobula to the medulla fails completely. Fibers enter the lobula but then either project to inappropriate sites within the lobula or stop at the lobula-medulla border. Expression of Fmr1Scer\UAS.cZa under the control of Scer\GAL4OK107 results in dramatic defects in the mushroom body axon lobes; the β lobe always overextends across the midline, the β' lobe often shows apparently random directions of axon projection which are often outside of the mushroom body domain and the γ lobe always shows a dramatic decrease in volume and is sometimes completely lost. The number of cell body processes produced by neuronal cells in the mushroom body is reduced 2-fold in single cell clones expressing Fmr1Scer\UAS.cZa under the control of Scer\GAL4OK107 compared to control single cell clones. The "claw-like" structure normally seen at the terminal of dendritic branches (this consists of a fine dendritic terminal arbor) is severely reduced or completely absent in the mutant cells. Single γ neurons in the mushroom body that express Fmr1Scer\UAS.cZa under the control of Scer\GAL4OK107 in an otherwise wild-type background show underbranching and dramatically reduced growth. Most of these mutant γ neurons maintain their process along the ventral edge of the horizontal lobe and aberrantly invade the β lobe. Flies that express Fmr1Scer\UAS.cZa, under the control of Scer\GAL4P2.4.Pdf, almost completely lack wild-type target innervation by the LNv. In the brains of flies that overexpress Fmr1Scer\UAS.cZa under the control of Scer\GAL4c747, there is a significant increase in the gap between the β lobes and between the γ lobes of the mushroom body. | |||

Genetic Interactions
| |||
Statement Reference Flies that co-express chicScer\UAS.cCa and Fmr1Scer\UAS.cZa, both under the control of Scer\GAL4P2.4.Pdf, show a wild-type-like pattern of LNv innervation. The LNv fasciculation phenotype seen when chicScer\UAS.cCa is expressed alone is suppressed. Coexpression of chicScer\UAS.cCa significantly reduces the mushroom body phenotype seen when flies overexpress Fmr1Scer\UAS.cZa under the control of Scer\GAL4c747. | |||
